Ring Joint System Anatomy

Design Features – Ring Welding

• Positioning of the Ring is done with Ring-Clamps
• Different versions available for Rigidity and Flexibility
• Workshop setup in-line makes welding efficient.

Welding Instruction

Option A

Main Weld + Back Weld

Option B

Back Weld + Main Weld

Option C

Main Weld only

Design Features

• Weld rings can provide higher service pressures than equivalent sized grooved joints
• Grooved system performance depends on the pipe wall thickness
• Thin wall pipe > pressure rating reductions
• Weld Ring can withstand 2 ~ 3 times the shearing force and end load of roll grooves
• Ring Joint system performance does not depend on pipe wall thickness.

• No pipe end flare
• No protrusion inside pipe
• Reduces flow interference
• Better Performance
• Longer Service Life

Design Features – Ring Welding

• Does not affect sealing ability of joint
• No need to inspect or x-ray the weld for leaks

• Time & Cost Savings
